IMPRO'V'ED BURGLARALARM.

The Schedule referred to in' these Letters Patent and making part of the same.

Be it known that we, WILLIAM H. EMMoNs, of the city, county, and State of New York, and FRANKLIN KISS'AM, ot' the city of Newark, county of Essex, and State of New J eusey, have invented a new and useful Improvement on Alarms for Safes,- Vaults, Banks, and Buildings, which we call a Burglar-Detector; and we do declare that the following is a full, clear, and. exact description of the construction and operation ot' thev same, reference being had to the annexed drawings, forming a part of these specifications.

Figure l shows an outside view of top, front, an( right-hand side of the ala-rin or detector, iu imitation of a pile of books.

Figure 2 is a section of iig. 1.

a represents a section of plates of glass, forming au inside case or box.

b, the outside case.

The other letters, described elsewhere, represent one method of arranging springs, cords, or wires, and levers, so as to let oii" the alarm.

Figure 3 shows a' section of aside elevation.

a', sectiorrof bell:

b', the standor post to which the bell is attached.

f, hollow shaft or pipe, with arms or levers.

k', pipe.

The dotted line, the spring driving the clock or alarm-movement, the dierent parts represented by the letters c', d', e', f', g', and h.

Figure 4 is a section of a front elevation.

c", the spring.

e", grooved pulley.

Ag", cord, for winding up clock or spring-movement, one end wound around pulley e, the other end attached to ring h".

The other letters are the different parts of acommon clock-alarm movement.

The outside case, seen in iig. 1, and in sections in figs. 2,v 3, and 4, marked b, can be made of any suita- Y ble material, as hardened-steel plates, chilled cast-iron, or common cast-iron, in almost any ornamental shape or form, as a pile ofbooks or bee-hive.

The inside case, a, shown in figs. 2, 3, and 4, in sections, should be made of thin glass, 'so as to break readily. It might be blown in the shape required, or plates can vbe cemented together.

The object f the glass case is to insure the sound ing of the alarm, by the breaking of glass on one side, in case the outer case be tampered with by means of a drill or hammer.

In tig. 2 is shown one method of arranging springs, cords, and levers, so as to cause the alarm to sound in case the glass b'e broken.

c, the springs, which can be made of brass, steel,l

have to be varied, according to the size of the bellv and its location. Where convenient, they can run straight from one side to another, and by the use oi' angled levers, any side can be connected with the alarm or levers in any position. y The alarm or detector can be placed on the outside of buildings, to call policemen or arouse neighborhoods it can be made to strike certain times, as a clock, or it can be put inside on safes, or connected with vaults, to frighten robbers and awake janitors.

In connecting it with a safe, a hole must be drilled through the top of the safe, the detector placed onl top, the pipe 7o', iigs. `3Aand 4,-passing through thehole, the lower arm or lever is then fastened to shaft j'. A catch is placed on the door of the safe, which, on the door being shut, catches the arm j. On opening the door,the arm is moved, and thealarm sounded. The sides ot' the safe can be protected in asimilar manner to that described for the glass case.

4 The spring or clock-movement is wound up from the inside of the safe or vault, by means of the cord i y, wound around and fastened to the pulley e, and

running through hole i in shaft j', and attached to ring h". The cord is -pulled to wind up the spring. \Ve thus avoid the danger of a key-hole.

Peribrations can be made in outer as well as inner case, so as to allow the sound to escape more freely, care being taken to not allow the openings, which must be small, of the outer to be near those of the inner case.

W'e do not claim, as original, an Valarm sounded simply by means of springs; neither do we claim the operation of winding a clock by means of a cord and pulley; but

fhat we do claim as our invention, is

1. An inner casing of glass, -to which the alarm is connected by cords or wires secured to it, so that upon the breaking ofthe glass, the alarm is sounded, and protected by the outer case, as shown and described.

2. In combination with the above, the hollow shaft, protected by the pipe, passing through a safe, and connecting the alarm with thedoor-lock or sides of the safe, and allowing the alarm to be woundup from the inside of the safe, or vault, or room, to which it may be attached.
